I'm attempting to build a system that will take a live feed from a drum kit. The system will then act as a beat slicer on specified segments which I specify it to record. I want to include onset detection so that the slice positions occur correctly. I have been studying Jean-Francois Charles paper "A Tutorial on Spectral Sound Processing Using Max/MSP and Jitter" which can be found at
along with Curtis Roads "The computer music tutorial" to get to grasp with FFT's.
If anyone could suggest alternative or further methods or papers which may help me to obtain a better understanding in this area it would be greatly appreciated!
